BACKGROUND Field of the Disclosure

The present disclosure relates to a dispenser system for dispensing afluid comprising a dispenser and an adaptor configured to cooperate withthe dispenser to support a cartridge containing fluid.

Description of the Background of the Disclosure

Dispensers are used in a wide variety of different environments, rangingfrom public bathrooms to office blocks, hotels, hospitals, restaurants,and other public or private establishments. Generally, dispensersconsist of a dispenser housing and a refillable and/or replaceablereservoir containing the fluid product to be dispensed (e.g., acartridge).

Depending on the location, the dispenser will likely be required todispense a particular type of fluid product, such as, e.g., soap,sanitizing solution, shampoo, etc. Furthermore, it is important that thefluid product dispensed is of a required quality and/or grade. This isparticularly important where hygiene is of high importance, such as,e.g., in a hospital setting, where it is important that only theexpected fluid is dispensed from the dispenser.

To this end, dispensers may be configured to operate exclusively withcartridges containing the particular fluid desired, which often resultsin the dispenser having complex mechanisms with multiple components forpreventing use of the dispenser with the wrong type of cartridge, i.e.,an incompatible cartridge.

However, manufacturing a corresponding dispenser tailored for useexclusively with a particular cartridge type is costly and requires alarge product range.

Furthermore, different grades or types of fluid products may be desired,which can require the replacement of the entire dispenser with a newdispenser that is compatible with the new cartridge, or replacement ofmechanisms within the dispenser, both of which are costly andinefficient.

It is an aim of the present disclosure to address or mitigate at leastsome of these problems.

In some embodiments, the adaptor is configured to bereceived within a first chassis, and the adaptor includes a central flexaxis that extends in a direction that is parallel with a direction inwhich the first chassis is configured to be translated.

In some aspects, the first chassis is configured to be translated in avertical direction. In some embodiments, the first leg and the secondleg each extend from opposing sides of the central portion. In someaspects, the adaptor is configured to be received within a U-shaped slotof the first chassis. In some embodiments, the first leg and the secondleg are each configured to be rotated about the central flex axis. Insome aspects, the central portion includes a first bias that isconfigured to resist movement of the first leg and the second leg aboutthe central flex axis. In some embodiments, the adaptor is configured tobe coupled to a pump drive flange of a cartridge containing a fluid tobe dispensed.

In yet another aspect, a dispenser includes a dispenser body that has aninterior cavity in which a first chassis is configured to be translatedrelative to a second chassis along a central axis. Further, thedispenser has a cartridge including a container and a pump that includesa drive flange defining a drive diameter. In addition, the dispenserincludes an adaptor having a pair of legs that are configured to becoupled to the drive flange and the first chassis, and the adaptor andthe drive flange are configured to prevent the drive flange from beingtranslated independently of each other.

In some embodiments, the first leg of the adaptor includes first andsecond retention projections, the second retention projection beingconfigured to contact the drive flange and the first retentionprojection being configured to contact the first chassis. In someaspects, the drive flange defines a diameter, the adaptor defines aretention width, and the diameter is configured to correspond to theretention width to achieve a snap-fit between the adaptor and the driveflange.

In some embodiments, an actuator is configured to be depressed to causetranslation of the first chassis, the adaptor, and the drive flange in afirst direction, at least one spring is configured to translate thefirst chassis, the adaptor, and the drive flange in a second directionopposite to the first direction, and the actuator is configured to bedepressed in a third direction that is different from the first andsecond directions.

In still another aspect, a method of providing a dispenser fordispensing a fluid includes the provision of a dispenser body and theprovision of a first adaptor that is configured to couple a firstcartridge to the dispenser body. The first adaptor defines a firstdimension that corresponds to a portion of the first cartridge. Further,the method includes the provision of a second adaptor that is configuredto couple a second cartridge to the dispenser body. The second adaptordefines a second dimension that corresponds to a portion of the secondcartridge. In some embodiments, the first dimension is different fromthe second dimension, and the first adaptor and the second adaptor areconfigured to be flexible.

In some embodiments, the first adaptor and the second adaptor aresubstantially identical to each other except for the first and seconddimensions. In some aspects, the first cartridge and the secondcartridge are different with respect to at least one of a pump, acartridge body, and a fluid to be dispensed. In some embodiments, thefirst dimension of the first adaptor does not correspond to the portionof the second cartridge and the second dimension of the second adaptordoes not correspond to the portion of the first cartridge.

In some aspects, when the first adaptor is operably received within thedispenser body, the first cartridge is capable of dispensing a fluid. Insome embodiments, only one of the first adaptor and the second adaptorcan be operably received within the dispenser body. In some aspects, thedispenser body includes a front cover that is rotatably mounted to aback body about a first hinge axis and the front cover includes anactuator that is rotatable about a second hinge axis that is spacedapart from the first hinge axis.

In some embodiments, the actuator is configured to contact a movingchassis within the dispenser body when the front cover is mounted to theback body in a closed position. In some aspects, in the closed position,when the actuator rotates about the second hinge axis, the movingchassis translates within the dispenser body. In some embodiments, inthe closed position, when the actuator rotates about the second hingeaxis, the first adaptor or the second adaptor, translates with themoving chassis.

In another aspect, a dispenser system comprising a dispenser fordispensing a fluid is provided, the dispenser system comprising adispenser body at least partially defining an interior of the dispenserwhich is configured to house a cartridge containing fluid to bedispensed. Further, the dispenser system includes a moving chassis thatis configured for movement with respect to the body and an adaptorconfigured to be removably coupled to the moving chassis to form asupport structure for supporting a cartridge of a predetermined type inthe dispenser. To that end, the adaptor cooperates with the movingchassis of the dispenser to form a support structure for supporting acartridge in the dispenser. Accordingly, a dispenser having a singlemoving chassis design can be adapted for use with a desired cartridgetype by use of the adaptor. Accordingly, for a variety of cartridgetypes corresponding to a variety of fluid products, a single dispenserand moving chassis design can be used and adapted to be compatible witha particular cartridge type by the use of a corresponding adaptor. As aresult, the dispenser is efficiently manufactured, cost effective, andconsolidates a quantity of parts, while being capable of use with avariety of cartridge types.

In some embodiments, the adaptor and moving chassis are coupled togetherto form a support structure for supporting a particular cartridge typeto maintain the integrity of the dispenser, such that users receive theexpected fluid during use. In addition, when a cartridge becomesdepleted, a full cartridge of identical type can replace the depletedcartridge for operable use within the dispenser. As such, the adaptorand the moving chassis are compatible with cartridge types and/orparticular cartridges.

Furthermore, in the event that the dispenser is required to dispense adifferent type of fluid, the adaptor can be replaced with an alternativeadaptor configured to support a different type of cartridge without theneed to replace the entire moving chassis or dispenser. Accordingly, thedispenser can be reconfigured to operate with a different type ofcartridge if required, and such reconfiguration can be carried out inplace. Further, in the event of lost or damaged parts, the adaptor canbe replaced without requiring replacement of the moving chassis ordispenser. This results in a versatile dispenser system of simpleconstruction that can be reconfigured efficiently by maintenanceprofessionals, which is more cost effective and less wasteful.

It will be appreciated that, by supporting the cartridge with thesupport structure, the cartridge is coupled to the moving chassis suchthat at least a portion of the cartridge is secured for movement withthe moving chassis. The adaptor and the moving chassis are coupledtogether such that movement of the moving chassis with respect to thebody causes movement of the adaptor with respect to the body. When acartridge is supported by the support structure, movement of the movingchassis therefore causes corresponding movement of the cartridge.

In some embodiments, both the moving chassis and adaptor must be presentin the dispenser to support the cartridge of a predetermined type in thedispenser for dispensing. To that end, the moving chassis and theadaptor cooperate to support the cartridge of a predetermined type.Without either component, the support structure is not formed and thecartridge of a predetermined type cannot be supported in the dispenserfor dispensing.

In some embodiments, the adaptor is configured to be removably coupledto the moving chassis such that movement of the moving chassis istranslated directly into movement of the adaptor throughout an entirerange of movement of the moving chassis. To that end, there is no lostmotion between the moving chassis and the adaptor. In some embodiments,the moving chassis is configured for vertical movement when in normaluse. In some embodiments, the moving chassis is not configured to beremoved from the dispenser. In some embodiments, the moving chassis isconfigured to be permanently coupled to the dispenser body.

In some embodiments, the support structure defines an opening forreceipt of said cartridge. In some embodiments, the adaptor isconfigured to flex in a direction toward and away from said opening. Insome embodiments, the adaptor is configured to flex toward and away froman opening defined by the support structure that is configured forreceipt of the cartridge. In this way, the adaptor is configured to flextoward and away from the cartridge when in use, thereby facilitatinglocation of the cartridge in the support structure to effectively loadthe cartridge in the body. This provides a simple and effective way ofloading the cartridge in the dispenser housing, while keeping the numberof moving parts and overall component numbers comprising the supportstructure to a minimum. For example, since the adaptor is configured toflex, additional springs are not required, thereby reducing the numberof components as well as the amount of metal required to construct thedispenser system.

In some embodiments, the adaptor is configured to flex relative to themoving chassis, when the adaptor is coupled to the moving chassis. Inother words, from the frame of reference of the moving chassis, theadaptor is configured to flex when it is coupled to the moving chassis.The fluid may comprise a soap, shampoo, hand sanitizer, lotion, cleaningagent or other desired fluid. As used herein, the term “soap” isintended to include any liquid detergent or cleaning product suitablefor being dispensed from a fluid dispenser.

In some embodiments, the support structure is configured to exclusivelysupport a cartridge of a predetermined type. Accordingly, the dispensersystem can be used exclusively with the correct cartridge type, ensuringthat the fluid being dispensed is as required and expected.

In some embodiments, the adaptor is configured for snap-fit engagementwith the cartridge. In some embodiments, the support structure isconfigured for snap-fit engagement with the cartridge. In this way, asimple and easy means of supporting the cartridge in the dispenser isprovided. It will be appreciated that the snap-fit functionality of theadaptor with the cartridge is facilitated by the adaptor beingconfigured to flex in a direction toward and away from the opening ofthe support structure.

In some embodiments, the adaptor comprises a catch element for engaginga corresponding portion of said cartridge. In this way, thecorresponding portion of the cartridge is coupled to the supportstructure for movement with the moving chassis. In some embodiments, thecatch element is biased toward engagement with said cartridge. Thisprovides a simple and effective means of retaining the cartridge inplace. In other words, the cartridge is more effectively coupled to thesupport structure.

In some embodiments, the adaptor comprises at least one resilient legextending from a central portion, wherein the leg is configured to flexabout the central portion. In some embodiments, the adaptor comprises apair of resilient legs configured to flex about the central portion.Accordingly, the resilient leg facilitates flexing of the adaptor in adirection toward and away from the opening of the support structure.This provides an adaptor with a simple structure which is configured toflex. In some embodiments, the resilient leg comprises the catchelement.

In some embodiments, the adaptor comprises a pair of legs arrangedsymmetrically about the central portion. In some embodiments, each ofthe pair of legs comprises a catch element. Accordingly, the resilientlegs are configured to flex toward and away from an axis of symmetry ofthe adaptor such that the catch elements are therefore arranged to movetoward and away from the axis of symmetry.

When a cartridge is loaded in the dispenser and the adaptor is coupledto the moving chassis, the pair of legs, and hence the catch elementsprovided thereon, are configured to flex in a direction toward and awayfrom the opening of the support structure, i.e., toward and away fromthe cartridge, e.g., a longitudinal axis of the cartridge. By providingopposing catch elements in this way, effective retention of thecartridge in place can be achieved. In some embodiments, a pair of catchelements are provided, for example diametrically opposite each otherwith respect to the axis of symmetry of the adaptor and/or opening ofthe support structure. Accordingly, the pair of catch elements can actto grip a portion of the cartridge to retain it in place.

In some embodiments, the catch element comprises a projection,projecting toward the axis of symmetry of the adaptor. In someembodiments, where a pair of catch elements are provided, the catchelements comprise projections configured to extend toward each other. Insome embodiments, at least a portion of the leg comprises a bow shapedprofile to facilitate flexing of the adaptor. Accordingly, the profileof the adaptor is formed to facilitate the flexing capability of theadaptor, such that no additional springs or components are required.This reduces the number of components required in the dispenser systemand also reduces the amount of metal required to manufacture thedispenser. The bow shaped profile also facilitates snap-fit engagementof the catch with the cartridge. In some embodiments, the supportstructure comprises a retention arrangement for coupling the adaptor tothe moving chassis. Accordingly, the adaptor and moving chassis arereliably coupled together.

In some embodiments, the retention arrangement comprises a snap-fitarrangement. In some embodiments, the retention arrangement is biasedtoward coupling of the adaptor and the moving chassis. Accordingly, asimple and effective way of coupling the adaptor and the moving chassisis provided. In some embodiments, the adaptor comprises a resilientlybiased structure comprising a retention element for coupling to acorresponding retention element of the moving chassis, wherein theretention element of the adaptor and the corresponding retention elementof the moving chassis comprise the retention arrangement.

In some embodiments, the retention arrangement comprises a projectionand corresponding aperture. For example, the retention element of theadaptor may comprise a projection and the corresponding retentionelement of the moving chassis may comprise an aperture, or vice versa.In some embodiments, the retention element of the adaptor is provided ata free end of the resilient leg. In some embodiments, a retentionelement of the adaptor is provided at a free end of each resilient leg.

In some embodiments, the moving chassis and adaptor comprise a locationarrangement for locating the adaptor in the correct position withrespect to the moving chassis. Accordingly, correct positioning of theadaptor with respect to the moving chassis can be achieved. Thisfacilitates correct location of the cartridge in the dispenser. In someembodiments, the location arrangement comprises a projection andcorresponding aperture or recess. For example, the adaptor may comprisethe projection and the moving chassis may comprise the aperture orrecess, or vice versa.

In some embodiments, the moving chassis comprises a cavity for receiptof the adaptor. In some embodiments, the location arrangement comprisesa locating element of the adaptor and a corresponding locating elementof the cavity. In some embodiments, the locating element of the adaptoris provided by the central portion of the adaptor. This facilitateseffective location of the adaptor with respect to the moving chassis.

In some embodiments, the location arrangement comprises a projection andcorresponding aperture or recess. For example, the locating element ofthe adaptor may comprise a projection and the corresponding locatingelement of the cavity may comprise an aperture or recess, or vice versa.In some embodiments, the adaptor is configured to be operatively coupledto the moving chassis such that the adaptor is secured for movement withthe moving chassis, and the adaptor is configured to engage a portion ofthe cartridge, such that movement of the moving chassis is translateddirectly into movement of the portion of the cartridge throughout anentire range of movement of the moving chassis.

In some embodiments, the moving chassis and adaptor are configured tomove together such that a portion of the cartridge which is supported bythe moving chassis and adaptor moves together with the moving chassisand adaptor. In some embodiments, the cartridge is supported by themoving chassis and adaptor such that movement of the moving chassis istranslated into movement of the portion of the cartridge throughout anentire range of movement of the moving chassis. Accordingly, there is noloss of motion between the portion of the cartridge and the movingchassis. This results in a consistent dose of fluid being dispensed fromthe dispenser.

In some embodiments, the adaptor comprises a single component.Accordingly, a dispenser system with a simple construction is provided.Furthermore, should the dispenser system need to be used with adifferent type of cartridge, this can be achieved simply by replacing asingle component, i.e., the adaptor, for an adaptor corresponding to thedesired cartridge type. This reduces the parts required for manufactureof the dispenser system in the first instance, and also reduces thenumber of parts that need to be replaced should a dispenser need to bereconfigured for use with a different cartridge type. This is more costefficient and reduces waste.

In some embodiments, the adaptor is formed of a plastic material. Thisfacilitates the resilient nature of the adaptor and also reduces theamount of metal required to produce the dispenser system. In someembodiments, the adaptor is a first adaptor configured to be removablycoupled to the moving chassis to form a support structure for supportinga first cartridge in the dispenser, and the dispenser system furthercomprises a second adaptor configured to be removably coupled to themoving chassis to form a support structure for supporting a secondcartridge, different to the first cartridge, in the dispenser, whereinthe first adaptor and second adaptor are arranged to be interchangeablycoupled to the moving chassis.

In a further aspect, a dispenser assembly is provided comprising adispenser system as disclosed herein and a cartridge containing fluid tobe dispensed. In some embodiments, the cartridge further comprises apump configured to dispense fluid from the cartridge, the pumpcomprising a movable component (e.g., comprising a piston) which isconfigured to be supported by the support structure for movement withthe moving chassis.

In some embodiments, the cartridge comprises a pump having a movablecomponent and a fixed component configured such that movement of themovable component with respect to the fixed component generates apumping action to dispense fluid from the cartridge. By supporting themovable component of the cartridge in the support structure, the movablecomponent is coupled for movement with the moving chassis, such that thepump action of the cartridge pump is achieved and fluid dispensed fromthe cartridge.

In some embodiments, the cartridge comprises a fixed portion (e.g.,comprising a cylinder of the pump) wherein the dispenser system isconfigured to retain the fixed portion of said cartridge againstmovement with respect to the dispenser housing. In some embodiments, thedispenser itself retains the fixed portion of the cartridge againstmovement. For example, the cartridge may comprise a cartridge bodylocated in the dispenser body, wherein the dispenser body itself (e.g.,an outer wall of the dispenser body) prevents movement of the cartridgebody with respect to the body.

In some embodiments, the fixed portion comprises a fixed portion of thecartridge pump. In some embodiments, the dispenser system (e.g., thesupport structure) comprises a static component configured to retain thefixed portion of the cartridge against movement with respect to thedispenser body. In some embodiments, the static component is integralwith the dispenser body.

In some embodiments, the cartridge and dispenser system (e.g., thesupport structure) comprise complimentary guide formations, such thatthe cartridge can only be loaded in the dispenser in a predeterminedorientation. Accordingly, incorrect loading of the cartridge in thedispenser housing is prevented or inhibited.

In a further aspect, a dispenser includes a body defining an interior ofthe dispenser which is configured to house a cartridge containing afluid to be dispensed. Further, the dispenser includes a moving chassisconfigured for movement with respect to the dispenser body, a firstadaptor configured to be removably coupled to the moving chassis to forma support structure for supporting a first cartridge in the dispenser,and a second adaptor configured to be removably coupled to the movingchassis to form a support structure for supporting a second cartridge,different to the first cartridge, in the dispenser. The first adaptorand second adaptor are arranged to be interchangeably coupled to themoving chassis. To that end, the moving chassis is arranged to cooperatewith both the first adaptor and the second adaptor, interchangeably. Thefirst adaptor, which is configured for operation with a first cartridge,can be replaced with the second adaptor, which is configured foroperation with a first cartridge, without needing the entire movingchassis or dispenser to be replaced, and vice versa.

Each of the first and second adaptors co-operates with the movingchassis of the dispenser to form a respective support structure forsupporting a respective type of cartridge in the dispenser. Accordingly,a dispenser having a single moving chassis design can be adapted for usewith a desired cartridge type via use of the adaptor. Consequently, fora given range of cartridges, e.g., corresponding to a given range offluid products, a single dispenser and moving chassis design can be usedand adapted to be compatible with a particular cartridge via acorresponding adaptor. This is simple to manufacture, more costeffective, and less wasteful.

The dispenser system can be easily re-configured to operate with adifferent type of cartridge if required. For example, it may be that thefirst cartridge comprises a first fluid type and the second cartridgecomprises a second fluid type. This results in a versatile dispensersystem of simple construction that can be easily re-configured tooperate with different cartridges with minimal changes to the system,which is more cost effective and less wasteful. Furthermore, use of thefirst and second adaptors ensures that only corresponding cartridges canbe used with the dispenser, ensuring that the quality, grade, and/ortype of fluid dispensed is as required.

In some embodiments, the first adaptor comprises a first retentionelement for coupling the first adaptor to the moving chassis and thesecond adaptor comprises a second retention element for coupling thesecond adaptor to the moving chassis, wherein the moving chassiscomprises a corresponding retention element which corresponds to thefirst retention element of the first adaptor and which also correspondsto the second retention element of the second adaptor, such that thefirst retention element and the second retention element are arranged tobe interchangeably coupled to the corresponding retention element of themoving chassis. To that end, the moving chassis comprises a singleretention element structure, which corresponds to both the firstretention element of the first adaptor and also the second retentionelement of the second adaptor, such that the moving chassis iscompatible with both the first and second adaptors. In other words, onlya single design of moving chassis is required that is compatible withboth the first and second adaptor retention elements.

In some embodiments, the moving chassis comprises a cavity for receiptof the first and/or second adaptor, wherein the first adaptor and secondadaptor are arranged to be interchangeably located in the cavity. Tothat end, the cavity of the moving chassis is configured to cooperatewith both the first and second adaptors, such that a single design ofmoving chassis can be used with both the first and second adaptors.

In some embodiments, the first adaptor comprises a first catch elementfor engaging a corresponding portion of said first cartridge, the secondadaptor comprises a second catch element for engaging a correspondingportion of said second cartridge, and the first catch element of thefirst adaptor and the second catch element of the second adaptor aredifferent. To that end, the first adaptor comprises a catch element thatis configured to engage a first cartridge and the second adaptorcomprises a catch element that is configured to engage a secondcartridge. The catch elements of the first adaptor and the secondadaptor are different such that they are configured to support differenttypes of cartridge. This allows the dispenser system to supportdifferent cartridge types simply by changing the adaptor which iscoupled to the moving chassis. This means that a single dispenser bodyand moving chassis design can be used to house a range of cartridgetypes. Only a corresponding adaptor will be required which is compatiblewith the desired cartridge type. Accordingly, a versatile dispensersystem is provided which reduces manufacturing requirements and alsoreduces cost and waste of materials.

In some embodiments, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 cartridgetypes may be included in a particular product range, for example,corresponding to different fluids. Accordingly, a corresponding numberof adaptors can be provided. It will be appreciated that any number ofcartridge types, configurations, or sizes may be included in a givenproduct range and that corresponding adaptors can be provided for eachcartridge type. In some embodiments, cartridges of the different typesmay include the same fluid but differing fluid volumes.

In some embodiments, the dispenser system comprises one or moreadditional adaptors configured to be removably coupled to the movingchassis to form a corresponding support structure for supporting arespective cartridge, wherein the first, second, and one or moreadditional adaptors are arranged to be interchangeably coupled to themoving chassis.

As illustrated in FIGS. 1 and 2 , the dispenser 110 includes a cover orfront panel 130 and a body 140 that includes a sidewall 144 extendingfrom a backplate 148 to at least partially define an interior cavity 152of the dispenser 110. The body 140 includes a bottom end 156 that isopposite a top end 160, a front end 164 that is opposite a rear end 168,and opposing sides 172. In the illustrated embodiment, the front panel130 is disposed at the front end 164, the backplate 148 is disposed atthe rear end 168, and the sidewall 144 extends between the front end 164and the rear end 168. In some implementations, the sidewall 144 isprovided as being translucent and transparent windows 176 are arrangedon the opposing sides 172, although other configurations are possible.

In one instance, the front panel 130 and the body 140 are movablerelative to each other between an open position (see FIG. 2 ), where theinterior cavity 152 is exposed and/or uncovered, and a closed position(see FIG. 1 ), where the interior cavity 152 of the dispenser 110 iscovered and/or concealed. In the closed position, the front panel 130spans across the front end 164, from the top end 160 to the bottom end156. Further, the sidewall 144 of the body 140 extends continuously fromthe top end 160 to the bottom end 156 in a generally U-shape, and anopening 180 is located at the top end 160 approximately centrallybetween the front and rear ends 164, 168 and between the opposing sides172. In the illustrated embodiment, the backplate 148 and the sidewall144 are integrally formed as a single component. However, it will beappreciated that the backplate 148 and the sidewall 144 may be providedas separate components and, further, that the sidewall 144 may beprovided as multiple portions or sections coupled together.

Referring to FIG. 1 , the front panel 130 and the body 140 mate togetheralong at least a portion of a periphery 184 formed between a perimeter188 of the front panel 130 and a peripheral edge 192 (see FIG. 2 ) ofthe sidewall 144, thereby causing a snug fit therebetween. In someembodiments, a gasket (not shown) of elastomeric material, or any othersuitable material, may be positioned between the front panel 130 and thebody 140 to prevent egress or ingress of liquids, gases, sounds, oroptical emissions. The gasket may be carried by the front panel 130and/or the body 140.

As illustrated in FIGS. 1 and 2 , a lock or release device 200 isdisposed within the opening 180 at the top end 160 of the body 140 and alatch or locking tongue 204 is carried by the front panel 130. FIG. 1illustrates the release device 200 in a first configuration in which abutton wall 208 is exposed at the sidewall 144. FIG. 2 illustrates therelease device 200 in a second configuration in which a key wall 212 isexposed at the sidewall 144 for use with a unique key (not shown).Together, the release device 200 and the locking tongue 204 comprise atleast part of a locking mechanism that is configured to releasablysecure the front panel 130 to the body 140 in the closed position.

With continued reference to FIGS. 1 and 2 , the front panel 130 includesa front wall 220 that spans across the perimeter 188. The perimeter 188of the front panel 130 includes a peak 224 that is located centrallythereon and at an uppermost point opposite a notch 228 formed at a lowersection 232. A trigger or actuator 236 is configured to be pivotablycoupled to the front panel 130 and mounted within the notch 228substantially flush with the front wall 220 and the perimeter 188 in thelower section 232. In the illustrated embodiment, the actuator 236 iscoupled to the front panel 130 in the lower section 232 by an actuatorhinge 240 from which lever arms 242 (see FIG. 2 ) protrude verticallyupwardly and outwardly for operable engagement with the body 140, aswill be described in more detail further below.

In the illustrated embodiment, the front panel 130 and the body 140 arepivotable or rotatable about an access hinge 244 at the bottom end 156of the body 140 to expose the interior cavity 152 and to permit accessthereto. The actuator hinge 240 is spaced apart from the bottom end 156and, thus, the actuator hinge 240 is spaced apart from the access hinge244 about which the body 140 and the front panel 130 are pivotable orrotatable. Additionally or alternatively, the front panel 130 and thebody 140 may be completely detachable from each other without the use ofthe hinge. In some embodiments, the front panel 130 may be adapted toslide relative to the body 140 to expose or cover the interior cavity152, or the front panel 130 may rotate in a different direction thanshown.

An example of the cartridge 120 which can be loaded into the dispenser110 is shown in FIG. 2 . The cartridge 120 includes an open mouth (notshown) defined by a neck 246 through which fluid leaves the cartridge120. The cartridge 120 may be formed as any suitable container, forexample, a bottle type container, although other configurations arepossible. The cartridge 120 also includes a pump 248 mounted within theopen mouth (not shown) of the neck 246 and configured to apply a suctionforce within a cartridge body 252 for pumping fluid therefrom,ultimately being pumped through a nozzle 256 to a user's handspositioned below the dispenser 110. Further, the pump 248 includes ahousing flange 260 that is secured to the neck 246 of the cartridge 120and protrudes outwardly therefrom. The cartridge 120 defines a centralaxis C extending generally vertically and axially through the neck 246and the cartridge body 252, as shown in FIG. 2 . In the illustratedembodiment, the nozzle 256 and the pump 248 are axially aligned with thecentral axis C, although other configurations are possible.

Still referring to FIG. 2 , a support structure 264 of the dispenser 110includes collar 266 carried by the body 140 and arranged to retain thehousing flange 260 of the cartridge 120 against movement with respect tothe dispenser 110. The cartridge 120 and the support structure 264include complimentary guide formations arranged such that the cartridge120 is loaded in the dispenser 110 in one or more predeterminedorientations. In one implementation, the neck 246 of the cartridge 120is provided with a pair of flat portions 268 and the dispenser 110includes a corresponding pair of guide projections 272. The flatportions 268 of the cartridge 120 and the corresponding guideprojections 272 of the dispenser 110 cooperate such that the cartridge120 is inserted into the dispenser 110 in one of two orientations. Inthe illustrated embodiment, the guide projections 272 are provided bythe collar 266 of the body 140, although other configurations arepossible.

FIGS. 3 and 4 illustrate the cartridge 120 being received by the supportstructure 264 of the body 140 of the dispenser 110 when the cartridge120 is moved into the interior cavity 152 of the body 140, as indicatedby the directional arrow of FIG. 2 . As best seen in FIG. 4 , thehousing flange 260 of the pump 248 is received within a correspondingpair of guide tracks 276 formed by the collar 266 and positioned belowthe guide projections 272. When the cartridge 120 is received in any ofthe predetermined orientations, the housing flange 260 is arranged toslide within the guide tracks 276 and to prevent vertical translation ofthe cartridge 120 relative to the dispenser 110. As such, the housingflange 260 has a predetermined diameter D1 and thickness T1 (see FIG. 11) corresponding with the dimensions of the guide tracks 276. Further,the housing flange 260 is configured to abut the neck 246 of thecartridge 120 to form a seal therebetween, thereby preventing fluid orair from escaping.

Referring again to FIG. 2 , the pump 248 is provided with a pump housing(not shown) that is coupled within the neck 246 of the cartridge 120 anda valve 284 that is movable within the pump housing (not shown). In theillustrated embodiment, the valve 284 carries a drive flange 288configured to move in relation to the housing flange 260 and, inparticular, the drive flange 288 moves vertically and concentricallywith respect to the housing flange 260. The drive flange 288 has apredetermined diameter D2 and thickness T2 (see FIG. 11 ) correspondingwith the dimensions of the support structure 264 of the dispenser 110for compatible operation therewith, which will be further describedbelow. However, it will be appreciated that any suitable pumpconstruction may be used to dispense fluid from the cartridge 120.Further, the pump 248 may be provided as a foam-type, a liquid-type, orany other suitable type of pump for dispensing a fluid-like product forconsumption.

It will be appreciated that the cartridge 120 is intended to berepresentative of various types and versions that may be used with thedispenser 110. Such types or versions of cartridges 120 may differ inparticular dimensions, i.e., the diameter D1 and thickness T1 of thehousing flange 260 or the diameter D2 and thickness T2 of the driveflange 288 (see FIG. 11 ), which correspond to particular compatibilityfeatures of the dispenser 110. Further, the types or versions ofcartridges 120 may vary with respect to the fluid contained therein, thetype of pump 248 used, the materials and/or construction of thecartridge body 252, or in other aspects.

In the illustrated embodiment of FIGS. 2-4 and 11-13 , the drive flange288 and the housing flange 260 are generally circular, although otherconfigurations are possible. For example, the drive flange 288 and/orthe housing flange 260 may instead be provided in the form ofrectangular tabs (not shown) or, alternatively, the drive flange 288and/or the housing flange 260 may be provided in a rectangular shape, ora triangular shape, or trapezoidal shape, or an irregular shape, or anyother suitable shape capable of having corresponding dimensions to thesupport structure 264 of the dispenser assembly 100. In addition, thepump 248 may be removably coupled to the neck 246 of the cartridge 120to be reusable with multiple cartridges 120 or, alternatively, the pump248 may be permanently or semi-permanently coupled to the neck 246 ofthe cartridge 120 and intended for use with one cartridge 120. In theillustrated embodiment, the pump 248 is coaxial with the central axis Cand extends substantially vertically through and outwardly from the neck246 of the cartridge 120, but other arrangements are possible. Forexample, the valve 284 and drive flange 288 may extend outwardly fromthe neck 246 of the cartridge 120 at an angle relative to the centralaxis C.

With reference to FIGS. 3 and 4 , the support structure 264 furtherincludes a drive unit 292 having a moving chassis 296 that is arrangedfor vertical translation within the interior cavity 152. Further, thedrive unit 292 includes an adaptor 300 that is configured to beremovably received within the moving chassis 296, such that the movingchassis 296 and adaptor 300 together are configured to receive andoperably engage a predetermined cartridge type in the dispenser 110. Inone instance, the moving chassis 296 is provided as a separate componentto the dispenser 110 and the collar 266 is integral with the dispenser110, but other configurations are possible. The adaptor 300 isconfigured to have dimensions that correspond to the drive flange 288for enabling compatible operation therewith, as will be furtherdescribed below.

Still referring to FIGS. 3 and 4 , the moving chassis 296 of the driveunit 292 defines a receptacle 304 configured for receiving an operablecomponent, e.g., the drive flange 288, of the cartridge 120, where theoperable component corresponds to the cartridge type. In the illustratedembodiment, the receptacle 304 is configured for receiving the driveflange 288 carried by and operably connected with the pump 248 of thecartridge 120 to dispense fluid. As illustrated in FIG. 2 , the driveunit 292 defines a drive axis A that is centrally located in thereceptacle 304 and extends vertically through the body 140 of thedispenser 110. When the cartridge 120 is located in the dispenser 110,the drive flange 288 of the cartridge 120 occupies the receptacle 304 ofthe support structure 264 and, as a result, the drive axis A of thedispenser 110 is coaxial with the central axis C of the cartridge 120,as best seen in FIG. 3 . Further, the moving chassis 296 is configuredto be translated in a vertical direction, i.e., along the drive axis A,relative to the collar 266, such as, e.g., by actuation of the dispenser110 to dispense fluid.

With reference to FIGS. 5 and 6 , the adaptor 300 includes a joint orcentral portion 308 that connects a first leg 312 to a second leg 316,both of which extend outwardly from opposite sides of the centralportion 308. In the illustrated embodiment, the adaptor 300 issymmetrical about a longitudinal axis S that is centrally disposedbetween the first leg 312 and the second leg 316 and intersects thecentral portion 308. However, in other embodiments, the adaptor 300 maybe asymmetrical or may be symmetrical about a different axis. The firstleg 312 and the second leg 316 are capable of being rotated about thecentral portion 308, causing the central portion 308 to bend or flex. Insome implementations, the first leg 312 and the second leg 316 also bendor flex when being rotated about the central portion 308. As shown inFIG. 5 , a central flex axis F is defined by the central portion 308 andextends vertically, perpendicularly to the longitudinal axis S. Each ofthe first leg 312 and the second leg 316 is configured to be displaced(e.g., rotated) about the central flex axis F. In one instance, each ofthe first leg 312 and the second leg 316 is rotated both inwardly, i.e.,toward each other, and outwardly, i.e., away from each other, about theflex axis F, as indicated by the bi-directional arrows.

Referring to FIG. 5 , the first leg 312 includes a first latch 324 at afirst distal end 328 that is opposite the central portion 308 and thesecond leg 316 includes a second latch 332 at a second distal end 336that is opposite central portion 308, the first latch 324 and the secondlatch 332 being provided for retention of the adaptor 300 within themoving chassis 296. The first latch 324 and the second latch 332 may beindividually referred to as retention projections or elements andcollectively referred to as a first pair of retention projections orelements. Each of the first latch 324 and the second latch 332 isgenerally triangular-shaped and extends from a first curved arm 340 anda second curved arm 344, respectively, connected to the respective firstdistal end 328 of the first leg 312 and the second distal end 336 of thesecond leg 316. In addition, the first distal end 328 and the seconddistal end 336 of the adaptor 300 are also provided as curved sections.The first latch 324 protrudes laterally outwardly, i.e., away from thelongitudinal axis S, from the first curved arm 340 and a first crevice348 is defined therebetween. Similarly, the second latch 332 protrudeslaterally outwardly, i.e., away from longitudinal axis S, from thesecond curved arm 344 and a second crevice 352 is defined therebetween.

Still referring to FIG. 5 , a first rib 356 extends laterally inwardly,i.e., toward the longitudinal axis S, from the first latch 324 towardthe first leg 312 for preventing the first latch 324 from becomingexcessively displaced (e.g., rotated). Similarly, a second rib 360extends laterally inwardly, e.g., toward the longitudinal axis S, fromthe second latch 332 toward the second leg 316 for preventing the secondlatch 332 from becoming excessively displaced (e.g., rotated). Moreover,a first tab 364 extends longitudinally outwardly, i.e., parallel to thelongitudinal axis S, from the first curved arm 340 and a second tab 370extends longitudinally outwardly, i.e., parallel to the longitudinalaxis S, from the second curved arm 344 to provide surfaces forbi-directional manipulation, such as by a user's fingers and/or thumb.In some embodiments, a range of rotation about the first distal flexaxis F1 and a range of rotation about the second distal flex axis F2 areequal. However, a range of rotation about the central flex axis F isgreater than the range of rotation of either the first distal flex axisF1 and the second distal flex axis F2.

It will be appreciated that the first latch 324 and the second latch 332are configured to be displaced relative to the central portion 308 byway of translation and rotation, e.g., bending or flexing, about thecentral flex axis F. Further, the first latch 324 is capable of beingdisplaced (e.g., rotated) about a first distal flex axis F1 that isdefined between the first curved arm 340 and the first distal end 328and extends vertically, perpendicularly to the longitudinal axis S.Similarly, the second latch 332 is capable of being displaced (e.g.,rotated) about a second distal flex axis F2 that is defined between thesecond curved arm 344 and the second distal end 336 and extendsvertically, perpendicularly to the longitudinal axis S. As shown inFIGS. 5 and 8 , the first latch 324 and the second latch 332 are spacedequidistant from the central portion 308, although other configurationsare possible. Further, the first latch 324 and the second latch 332 arespaced apart from each other a distance W, which is greater than thedistance that either the first latch 324 or the second latch 332 isspaced from the central portion 308.

In the illustrated embodiment, the first latch 324 and the second latch332 are capable of being displaced both inwardly, i.e., toward eachother, and outwardly, i.e., away from each other, about the central flexaxis F by displacement (e.g., rotation) of the first leg 312 and thesecond leg 316, respectively. Further, the first latch 324 is capable ofbeing rotated both inwardly, i.e., toward the longitudinal axis S, andoutwardly, i.e., away from the longitudinal axis S, about the firstdistal flex axis F1. Still further, the second latch 332 is also capableof being rotated both inwardly, i.e., toward the longitudinal axis S,and outwardly, i.e., away from the longitudinal axis S, about the seconddistal flex axis F2. Accordingly, displacement of the first latch 324can occur as a result of its dependency on the first leg 312, such thatwhen the first leg 312 is displaced about the central flex axis F and/orthe central portion 308, the first latch 324 is also displaced. Thus, aposition of the first latch 324 is a function of a position of the firstleg 312 relative to the longitudinal axis S and/or the second leg 316.Further, displacement of the second latch 332 can occur as a result ofits dependency on the second leg 316, such that when the second leg 316is displaced about the central flex axis F and/or the central portion308, the second latch 332 is also displaced. Thus, a position of thesecond latch 332 is a function of a position of the second leg 316relative to the longitudinal axis S and/or the first leg 312. Inaddition, the distance W between the first latch 324 and the secondlatch 332 is a function of the position of the first leg 312 and thesecond leg 316 relative to the central portion 308 and the central flexaxis F, such that rotation can increase or decrease the distance Wbetween the first latch 324 and the second latch 332. In a similarfashion, rotation of the first latch 324 about the first curved arm 340and the first distal flex axis F1, as well as rotation of the secondlatch 332 about the second curved arm 344 and the second distal flexaxis F2, can increase or decrease the distance between the first latch324 and the second latch 332.

In addition, the first latch 324 is capable of being displacedindependently of the first leg 312 and independently of the central flexaxis F. That is, independent displacement of the first latch 324 canoccur about the first distal flex axis F1, without effect to theposition of the first leg 312 and the second leg 316. In addition, thesecond latch 332 is capable of being displaced independently of thesecond leg 316 and independently of the central flex axis F. That is,independent displacement of the second latch 332 can occur about thesecond distal flex axis F2, without effect to the position of the secondleg 316 and the first leg 312. It will also be appreciated that thefirst latch 324 and the second latch 332 can be displaced independentlyof each other about the first distal flex axis F1 and second distal flexaxis F2, respectively.

In the illustrated embodiment of FIG. 5 , the first latch 324 and thesecond latch 332 are positioned rearward of the first curved arm 340 andthe second curved arm 344, while the first leg 312 including the firstlatch 324 and the second leg 316 including the second latch 332 arepositioned forward of the central portion 308. Further, the first curvedarm 340 and the second curved arm 344 are each curved in the rearwarddirection opposite to the forward direction in which the central portion308 curves. As a result of these relative positions and curvatures,clockwise and counterclockwise rotation of the first latch 324 about thefirst curved arm 340, i.e., the first distal flex axis F1, causesdisplacement to occur in an opposite direction as compared to thecentral portion 308, i.e., the central flex axis F. Similarly, clockwiseand counterclockwise rotation of the second latch 332 about the secondcurved arm 344, i.e., the second distal flex axis F2, causesdisplacement to occur in an opposite direction as compared to thecentral portion 308, i.e., the central flex axis F. For example,clockwise rotation of the first latch 324 about the first distal flexaxis F1 causes laterally inward displacement of the first latch 324, butclockwise rotation of the first latch 324 by way of the first leg 312about the central portion 308 and/or central flex axis F causeslaterally outward displacement of the first latch 324. In a similarmanner, clockwise rotation of the second latch 332 about the seconddistal flex axis F2 causes laterally outward displacement of the secondlatch 332, but clockwise rotation of the second latch 332 by way of thefirst leg 312 about the central flex axis F causes laterally inwarddisplacement of the first latch 324. It will be appreciated that theinverse is true of counterclockwise rotation of the first latch 324relative to each of the central portion 308 and/or the central flex axisF and the first curved arm 340 and/or first distal flex axis F1 and,further, of counterclockwise rotation of the second latch 332 relativeto each of the central portion 308 and/or the central flex axis F andthe second curved arm 344 and/or second distal flex axis F2.

FIG. 5 depicts a rest position of the adaptor 300. By way of the arcuateor curved shape of the central portion 308, as well as the materials,thickness, and dimensions thereof, the central portion 308 defines acentral biased region 374 that imparts a resistance against displacement(e.g., rotation) of each of the first leg 312 and the second leg 316from the rest position, thereby causing springback to occur upondisplacement in any direction therefrom. Accordingly, that resistancemust be overcome for each of the first leg 312 and the second leg 316 tobe displaced (e.g., rotated) about the central flex axis F, whetherbeing rotated laterally inwardly or laterally outwardly. In this way,each of the first leg 312 and the second leg 316 is configured to springor snap back into the rest position from a displaced position by thecentral portion 308 and, in particular, by the resistance imparted toeach of the first leg 312 and the second leg 316 from the central biasedregion 374 of the central portion 308. Further, the central biasedregion 374 is configured to allow the first latch 324 and the secondlatch 332, i.e., the first pair of projections, to move relative to eachother by way of the first leg 312 and the second leg 316.

Further, by way of the arcuate or curved shape of the first curved arm340 and the first distal end 328, as well as the materials, thickness,and dimensions thereof, a first distal biased region 378 is formed bythe first curved arm 340 and the first distal end 328. The first distalbiased region 378 is intersected by the first distal flex axis F1 andimparts a resistance against displacement (e.g., rotation) of the firstlatch 324 from the rest position about the first distal flex axis F1,thereby causing springback to occur upon displacement in any directiontherefrom. Accordingly, that resistance must be overcome for the firstlatch 324 to be displaced (e.g., rotated) about the first distal flexaxis F1, whether being rotated laterally inwardly or laterallyoutwardly. Accordingly, the first latch 324 is configured to spring orsnap back into the rest position from a displaced position by the firstcurved arm 340 and, in particular, by the resistance imparted to thefirst latch 324 from the first distal biased region 378 of the firstcurved arm 340 during displacement. As will be appreciated from FIG. 5 ,the first distal biased region 378 is connected to the central biasedregion 374 by the first leg 312 and can be displaced (e.g., rotated)about the central flex axis F by way of the first leg 312. In thismanner, the first distal biased region 378, including the first distalflex axis F1, can be rotated about the central flex axis F and/or thecentral biased region 374.

In a similar fashion, by way of the arcuate or curved shape of thesecond curved arm 344 and the second distal end 336, as well as thematerials, thickness, and dimensions thereof, a second distal biasedregion 382 is formed by the second curved arm 344 and the second distalend 336. The second distal biased region 382 is intersected by thesecond distal flex axis F2 and imparts a resistance against displacement(e.g., rotation) of the second latch 332 from the rest position, therebycausing springback to occur upon displacement in any directiontherefrom. Accordingly, that resistance must be overcome for the secondlatch 332 to be displaced (e.g., rotated) about the second distal flexaxis F2, whether being rotated laterally inwardly or laterallyoutwardly. Accordingly, the second latch 332 is configured to spring orsnap back into the rest position from a displaced position by the secondcurved arm 344 and, in particular, by the resistance imparted to thesecond latch 332 from the second distal biased region 382 of the secondcurved arm 344 during displacement. As will be appreciated from FIG. 5 ,the second distal biased region 382 is connected to the central biasedregion 374 by the second leg 316 and can be displaced (e.g., rotated)about the central flex axis F by way of the second leg 316. In thismanner, the second distal biased region 382, including the second distalflex axis F2, can be rotated about the central flex axis F and/or thecentral biased region 374.

It is contemplated that the central biased region 374 imparts a firstresistance that is different than a second resistance imparted by thefirst distal biased region 378 and a third resistance imparted by thesecond distal biased region 382 or, alternatively, that the centralbiased region 374 may impart an equal magnitude of resistance asimparted by the first distal biased region 378 and/or the second distalbiased region 382. It is further contemplated that the first distalbiased region 378 and the second distal biased region 382 impart equalmagnitudes of resistance, although in some cases the second resistanceof the first biased region 378 is different from the third resistance ofthe second distal biased region 382 without departing from the scope ofthis disclosure. Further, a first range of rotation allowed by thecentral biased region 374 may be greater than a second range of rotationallowed by the first distal biased region 378 and a third range ofrotation allowed by the second distal biased region 382. In someembodiments, range of rotation is proportional to resistance, such thatgreater resistance results in lower range of rotation. In this way,different resistances can be related to different ranges of rotation.

Still referring to FIG. 5 , the adaptor 300 defines a height HO thatvaries therealong. In one instance, the height HO is identical along thefirst leg 312 and the second leg 316 but smaller at the central portion308. In particular, the reduced height HO of the adaptor 300 at thecentral portion 308 is provided for engagement with a locator 386 thatextends from the moving chassis 296 into a pocket 390 that is configuredto receive the central portion 308, as seen in FIG. 8 . In theembodiment of FIG. 5 , the first leg 312 and the second leg 316 eachinclude a plurality of protrusions 396 extending therefrom, which may bespaced apart from each other and positioned along one or more surfacesof the first leg 312 and the second leg 316, respectively. In theillustrated embodiment, the plurality of protrusions 396 are disposed ona top surface 400 and a bottom surface (not shown) of each of the firstleg 312 and the second leg 316, although other configurations arepossible.

Staying with FIG. 5 , the adaptor 300 comprises a first catch 404provided on the first leg 312 and a second catch 408 provided on thesecond leg 316 for retention of the drive flange 288. The first catch404 and the second catch 408 may be individually referred to asretention projections or elements and collectively referred to as asecond pair of retention projections or elements. Further, it will beappreciated that the first leg 312 includes the first latch 324 and thefirst catch 404, otherwise referred to as the first set of retentionprojections or elements, and the second leg 316 includes the secondlatch 332 and the second catch 408, otherwise referred to as the secondset of retention projections or elements. In the illustrated embodiment,the first catch 404 and the second catch 408 are spaced equidistant fromthe central portion 308 and between the central portion 308 and thefirst distal end 328 and the second distal end 336, respectively, of thefirst leg 312 and the second leg 316, respectively. Referring to theadaptor 300 of FIG. 5 , the first catch 404 and the second catch 408each extend laterally inwardly toward each other to define apredetermined dimension or distance E1, which is a retention width. Inone instance, the first catch 404 includes a first ramp 412 that extendsto a first tip 416 and a first channel 420 is defined underneath thefirst catch 404 between the first leg 312 and the first tip 416.Similarly, the second catch 408 includes a second ramp 424 that extendsto a second tip 428 and a second channel 432 (see FIG. 7 ) that isdefined underneath the second catch 408 between the second leg 316 andthe second tip 428. The first ramp 412 and the second ramp 424 eachextend downwardly and laterally inwardly from the top surface 400 of theadaptor 300 to the first tip 416 and the second tip 428, respectively.Further, the first catch 404 and the second catch 408 are arranged onthe adaptor 300 to define a channel height EE1 (see FIG. 11 ) that isless than the height HO of the adaptor 300.

With respect to the adaptor 300 of FIG. 5 , the predetermined distanceE1 is measured between the first leg 312 within the first channel 420 ofthe first catch 404 and the second leg 316 within the second channel 432of the second catch 408 (see FIG. 11 ). In this way, the adaptor 300 isconfigured with a predetermined dimension, i.e., distance E1 (see FIG.11 ), for compatibility with one or more predetermined cartridge types,such that a cartridge type that is compatible with the dispenserassembly 100 and the adaptor 300 will have corresponding dimensions tothe predetermined distance E1 and a cartridge that is not compatiblewill not have corresponding dimensions to the predetermined distance E1.In the illustrated embodiment, the predetermined distance E1 is providedto correspond with the diameter D2 of the drive flange 288 of thecartridge 120 (as illustrated in FIG. 11 ), such that the first catch404 and the second catch 408 contact the drive flange 288 for movementtherewith. Further, the channel height EE1 is provided to correspondwith the thickness T2 of the drive flange 288 of the cartridge 120, suchthat the first catch 404 and the second catch 408 receive the driveflange 288 within the first channel 420 and the second channel 432. Inthis way, the drive flange 288 is configured to be compatible with theadaptor 300, having corresponding dimensions for enabling compatibleoperation therewith. It is contemplated that the adaptor 300, includingthe first leg 312 and the first catch 404 and the second leg 316 and thesecond catch 408, can be differently shaped and sized to define a largeror smaller channel height EE1 or multiple channel heights. Further, itis contemplated that the drive flange 288 may be differently sized andshaped to define multiple thicknesses T2 and/or multiple diameters D2 tocorrespond to the adaptor 300. Accordingly, the adaptor 300 and thedrive flange 288 can be provided in a variety configurations, i.e.,shapes and sizes, to achieve an operable engagement with one another.

With reference to FIG. 6 , the moving chassis 296 includes a slot 436for receiving the adaptor 300, as indicated by the directional arrow. Inthe illustrated embodiment, the slot 436 is defined between an uppermember 440 and a lower member 444 that is opposite the upper member 440,the lower member 444 defining a lower surface 448 and a recessed edge452 that extends about the receptacle 304. In one instance, the uppermember 440 and the lower member 444 are generally U-shaped, althoughother configurations are possible. The upper member 440 has a lip 456that extends about the receptacle 304 and varies in height as itprotrudes vertically upward from the upper member 440. In addition, themoving chassis 296 has a forward end 458 that is arranged adjacent tothe front panel 130 when the dispenser assembly 100 is in a closedposition (see FIG. 14 ).

In addition, the moving chassis 296 has a back end 464 that includesspring posts 468 that are each configured to receive a spring 472 (seeFIG. 14 ). As illustrated in FIG. 6 , the spring posts 468 each aregenerally conical structures that become narrower as they extendvertically upward from a spring seat 476 that is partially surrounded bya curved border 480. Further, the back end 464 of the moving chassis 296includes a shaft 484 formed by a pair of shaft walls 488, which areL-shaped and extend from a central member 492, and a gap 496 extendsbetween the pair of shaft walls 488. The shaft 484 is configured to becoupled to a rail (not shown) of the body 140 for translationtherealong, such as, e.g., sliding, although other configurations arepossible.

Referring to FIGS. 6 and 7 , the moving chassis 296 also includes a pairof actuation docks 500 that each have opposing inner walls 504 and outerwalls 508. An angled docking wall 512 extends from an upper end 516 thatspans between the inner wall 504 and the outer wall 508. Further, anarcuate brace 520 extends between the inner wall 504 and the outer wall508 below the upper end 516. In the illustrated embodiment, the angleddocking wall 512 extends vertically upwardly and forwardly relative tothe upper end 516 of the actuation dock 500, and an actuation surface524 (see FIG. 7 ) extends continuously from the angled docking wall 512to the upper end 516. The actuation docks 500 are configured to receivethe lever arms 242 (see FIG. 14 ) of the actuator 236, such that whenthe front panel 130 is pivoted about the body hinge (not shown) towardthe body 140 the lever arms 242 are brought into contact with theactuation surface 524 of the angled docking walls 512. Further, as thefront panel 130 is further pivoted to the closed position, the leverarms 242 slide from the angled docking walls 512 to the upper end 516 ofthe actuation docks 500 while maintaining contact with the actuationsurface 524. In this way, the lever arms 242 are positioned for operableengagement with the moving chassis 296.

As illustrated in FIGS. 7 and 8 , the adaptor 300 is configured to bereceived by the moving chassis 296 to form the drive unit 292 of thesupport structure 264. The height HO (see FIG. 5 ) of the adaptor 300corresponds to a height of the slot 436 for receiving the adaptor 300therein without excess friction, e.g., in a clearance fit. In addition,the central portion 308 and part of the first leg 312 and the second leg316 are received within a pocket 390 formed by pocket walls 528 (seeFIG. 8 ) at the back end 464 of the moving chassis 296, where thereduced height HO of the adaptor 300 at the central portion 308corresponds to the locator 386 to prevent unauthorized or improperadaptors from being operably received within the slot 436, and also toensure proper installation of the adaptor 300.

Referring to FIG. 8 , the first catch 404 and the second catch 408 arelocated opposite one another relative to the receptacle 304 andequidistant from the central flex axis F of the central portion 308. Dueto the arcuate shape of the first leg 312 and the second leg 316, theadaptor 300 partially surrounds the receptacle 304 of the moving chassis296 while allowing space within the slot 436 for laterally outwarddisplacement of each of the first leg 312 and the second leg 316 aboutthe central flex axis F.

As best seen in the sectional view of FIG. 8 , the first latch 324 isreceived within a first aperture 532 defined between a first bumper 536and a first side 540 of the moving chassis 296. Similarly, the secondlatch 332 is received within a second aperture 544 defined between asecond bumper 548 and a second side 552 of the moving chassis 296. Toaccomplish insertion of the adaptor 300 within the slot 436, the firstlatch 324 and the second latch 332 slide along the first side 540 andthe second side 552, respectively, at the front end 458 of the movingchassis 296, which causes laterally inward displacement of the firstlatch 324 and the second latch 332. Upon reaching the first aperture 532and the second aperture 544, the first latch 324 and the second latch332 snap back into the rest position due to the resistance imparted bythe first distal biased region 378 and the second distal biased region382, such that the first latch 324 extends into the first aperture 532and the second latch 332 extends into the second aperture 544. In thisway, the adaptor 300 is coupled to the moving chassis 296.

In the illustrated embodiment of FIG. 8 , when the adaptor 300 isreceived within the slot 436 and coupled to the moving chassis 296 priorto engagement with the drive flange 288, the first crevice 348 is spacedapart from the first side 540 of the moving chassis 296 and the secondcrevice 352 is spaced apart from the second side 552 of the movingchassis 296. In addition, due to the shape and size of the adaptor 300,a spacing is provided between the first bumper 536 and the first latch324 and between the second bumper 548 and the second latch 332. Further,there is a spacing between the first leg 312 and the adjacent pocketwalls 528 and between the second leg 316 and the adjacent pocket walls528, such that laterally outward displacement (e.g., rotation) can occurabout the central flex axis F while the adaptor 300 is received withinthe slot 436 and coupled to the moving chassis 296. In this way, theadaptor 300 is configured to flex within the slot 436 of the movingchassis 296 while simultaneously being coupled to the moving chassis296.

In addition, the adaptor 300 is configured to be removed from the slot436 by displacement of the first leg 312 and the second leg 316. This isaccomplished by a user squeezing the tabs 364, 370 together to cause thefirst leg 312 and the second leg 316 to be displaced laterally inwardly,e.g., toward each other, which causes the first latch 324 and the secondlatch 332 to be displaced from the first aperture 532 and the secondaperture 544, respectively. Then, the user removes the adaptor 300 fromthe slot 436 of the moving chassis 296 and releases the tabs 364, 370,allowing the first leg 312 and the second leg 316 to spring back intothe rest position.

As illustrated in FIGS. 7 and 8 , the drive axis A is approximatelycentrally positioned within the receptacle 304 and approximatelycentrally disposed between the central flex axis F and both of the firstdistal flex axis F1 and the second distal flex axis F2 of the adaptor300 when operably received within the slot 436 of the moving chassis296. In the illustrated embodiment, the central flex axis F and both ofthe first distal flex axis F1 and the second distal flex axis F2 areparallel with the drive axis A, such that displacement (e.g., rotation)occurs about these vertical axes. Accordingly, the adaptor 300 isconfigured to be translated vertically by way of its position within theslot 436 of the moving chassis 296 while simultaneously being configuredto flex about the central flex axis F, as described below with respectto FIGS. 11-13 .

FIG. 9 illustrates another embodiment of an adaptor 600 that isconfigured to be received within the slot 436 of the moving chassis 296for use with a compatible cartridge 120, as shown with respect to theadaptor 300 in FIGS. 6-8 . Referring to FIG. 9 , the adaptor 600 issubstantially identical to the adaptor 300 of FIGS. 5-8 , except thatthe adaptor 600 is configured to be compatible with a differentcartridge than the adaptor 300 of the first embodiment. In particular,the adaptor 600 includes a first catch 604 that extends laterallyinwardly farther than the first catch 404 of the first embodiment of theadaptor 300, and a second catch 608 that extends laterally inwardlyfarther than the second catch 408 of the first embodiment of the adaptor300. Further, the first catch 604 includes a first ramp 612 that extendsdownwardly and laterally inwardly toward a first tip 616 and the secondcatch 608 includes a second ramp 620 that extends downwardly andlaterally inwardly toward a second tip 624. In addition, the first catch604 includes a first base member 628 that extends laterally inwardlyfrom the first leg 312 approximately halfway (½) between the first leg312 and the first tip 616, and the second catch 608 includes a secondbase member 632 that extends laterally inwardly from the second leg 316approximately halfway (½) between the second leg 316 and the second tip624. A predetermined distance E2, which is a retention width, is definedbetween the first base 628 of the first catch 604 and the second base632 of the second catch 608. Further, a cavity 640 is formed adjacenteach of the first catch 604 and the second catch 608, respectively, ofthe adaptor 600, such that the first catch 604 and the second catch 608are generally hollow. In addition, a first rib 644 extends inwardly fromthe first leg 312 at an angle relative to the longitudinal axis S and asecond rib 648 extends inwardly from the second leg 316 at an anglerelative to the longitudinal axis S. The first rib 644 and the secondrib 648 are configured to abut the drive flange 288 of the cartridge 120that is sized and shaped to be compatible with the adaptor 600. Inparticular, the diameter D2 of the drive flange 288 corresponds to thepredetermined distance E2 for compatible operation with the adaptor 600.In this way, the first rib 644 and the second rib 648 allow the driveflange 288 to be more easily captured between the first catch 604 andthe second catch 608 while also preventing tilting or rotation relativeto the adaptor 600.

FIG. 10 illustrates yet another embodiment of an adaptor 700 that isconfigured to be received within the slot 436 of the moving chassis 296for use with a compatible cartridge type. The adaptor 700 issubstantially identical to the adaptor 300 of FIGS. 5-8 and the adaptor600 of FIG. 9 , except that the adaptor 700 is configured to becompatible with a different cartridge than both the adaptor 300 of thefirst embodiment and the adaptor 600 of the second embodiment. Inparticular, the adaptor 700 includes a first catch 704 that extendslaterally inwardly farther than the first element 604 of the secondembodiment of the adaptor 600, and a second catch 708 that extendslaterally inwardly farther than the second catch 608 of the secondembodiment of the adaptor 600. Further, the first catch 704 includes afirst ramp 712 that extends downwardly and laterally inwardly toward afirst tip 716 and the second catch 708 includes a second ramp 720 thatextends downwardly and laterally inwardly toward a second tip 724. Inaddition, the first catch 704 includes a first base member 728 thatextends laterally inwardly from the first leg 312 approximatelytwo-thirds (⅔) between the first leg 312 and the first tip 716 to form afirst channel 730 therebetween and the second catch includes a secondbase member 732 that extends laterally inwardly from the second leg 316approximately two-thirds (⅔) between the second leg 316 and the secondtip 724 to form a second channel 734 therebetween. A predetermineddistance E3, which is a retention width, is defined between the firstbase member 728 of the first catch 704 and the second base member 732 ofthe second catch 708. Further, a cavity is 740 formed adjacent each ofthe first catch 704 and the second catch 708, respectively, of theadaptor 700, such that the first catch 704 and the second catch 708 aregenerally hollow. In addition, a first rib 744 extends inwardly from thefirst leg 312 at an angle relative to the longitudinal axis S and asecond rib 748 extends inwardly from the second leg 316 at an anglerelative to the longitudinal axis S. The first rib 744 and the secondrib 748 are configured to abut the drive flange 288 of another cartridge120 that is compatible with the adaptor 700. In particular, the diameterD2 of the drive flange 288 corresponds to the predetermined distance E3for compatible operation with the adaptor 700. In this way, the firstrib 744 and the second rib 748 allow the drive flange 288 to be moreeasily captured between the first catch 704 and the second catch 708while also preventing tilting or rotation relative to the adaptor 700.

As can be appreciated from FIGS. 5, 9, and 10 , the predetermineddistance E2 is greater than the predetermined distance E3 and less thanthe predetermined distance E1. The predetermined distances E1, E2, andE3 of the adaptors 300, 600, and 700, respectively, may range from about0.3 inch (7.62 mm) to about 2 inches (50.8 mm), although otherconfigurations are possible. In one instance, the predetermined distanceE1 is about 1 inch (25.4 mm), the predetermined distance E2 is about0.85 inch (21.59 mm), and the predetermined distance E3 is about 0.7inch (17.78 mm), although other configurations are possible. It iscontemplated that the drive flange 288 may have a diameter D2 in a rangeof about 0.3 inch (7.62 mm) to about 2 inches (50.8 mm) and, preferably,within a range of about 0.7 inch (17.78 mm) to about 1 inch (25.4 mm).

As illustrated in FIGS. 11-13 , when the drive flange 288 is compatiblewith the adaptor 300 that is present within the slot 436 of the movingchassis 296, such that the predetermined distance E1 corresponds to thediameter D2, the drive flange 288 is configured to slide over each ofthe first and second catch 404, 408 to become captured within the firstand second channels 420, 432 and secured to the moving chassis 296.Further, as the drive flange 288 slides over each of the first andsecond catch 404, 408, each of the first leg 312 and the second leg 316is displaced (e.g., rotated) outwardly about the central flex axis F andagainst the resistance imparted by the central biased region 374 (seeFIG. 5 ) of the central portion 308, as well as any additive resistanceprovided by the material, thickness, dimensions, and curvature of thearcuate shape of each of the first leg 312 and the second leg 316.

Referring to FIG. 11 , with the cartridge 120 installed within thesupport structure 264 of the body 140 in an inverted orientation withinthe dispenser 110, the housing flange 260 is received within the guidetracks 276 of the collar 266 and the flat portions 268 of the neck 246are received by the guide projections 272 of the collar 266. In thisinstalled position, the central axis C of the cartridge 120 is alignedwith the drive axis A of the drive unit 292, such that the drive flange288 of the pump 248 is coaxial with the drive axis A. However, asdepicted in FIG. 11 , the pump 248 is in a pre-primed state in which thevalve 284 is fully retracted within the pump housing (not shown). As aresult, the drive flange 288 is spaced apart vertically from the adaptor300 and the receptacle 304 and, more specifically, the drive flange 288is positioned above the adaptor 300 and below the collar 266. FIG. 11illustrates that the housing flange 260 has a thickness T1 and diameterD1, that the drive flange 288 has a thickness T2 and diameter D2, andthat the adaptor 300 has a predetermined distance E1, which issubstantially equivalent or equal to the diameter D2 of the drive flange288. As a result, the adaptor 300 and the drive flange 288 shown arecompatible. If the drive flange 288 was of a smaller diameter D2 and,thus, was incompatible, the first and second catches 404, 408 of theadaptor 300 would pass the drive flange 288 without contact, renderingthe drive flange 288 inoperable with the drive unit 292. Alternatively,if the drive flange 288 was of a larger diameter D2 and, thus, wasincompatible, the first and second catches 404, 408 would be unable totranslate above the drive flange 288 and no sliding engagement wouldoccur, i.e., the drive unit 292 would jam. In the illustratedembodiment, because the valve 284 is fully retracted within the pumphousing (not shown) of the cartridge 120, the valve 284 and, thus, thedrive flange 288 is prevented from translating vertically upward.

FIG. 12 illustrates a capture stage of the dispenser assembly 100 inwhich the actuator 236 has been depressed in a substantiallylongitudinal direction, e.g., rearward, to rotate about the actuatorhinge 240 of the front panel 130 for exerting a vertically upward forceupon the drive unit 292 by way of the lever arms 242. In the illustratedembodiment, the drive unit 292, i.e., the moving chassis 296 and theadaptor 300, is translated vertically upward to capture the drive flange288 between the first leg 312 and the second leg 316 of the adaptor 300and between the first catch 404 and the second catch 408. In addition,the drive flange 288 is captured within the first channel 420 and thesecond channel 432 of the adaptor 300 such that it is secured betweenthe first catch 404 and the moving chassis 296 as well as between thesecond catch 408 and the moving chassis 296. At the stage of FIG. 12 ,the adaptor 300 has been translated vertically, i.e., lifted, to causethe drive flange 288 to slide along the first ramp 412 and the secondramp 424, which results in the first leg 312 and the second leg 316becoming displaced (e.g., rotated) about the central axis F. After thefirst tip 416 and the second tip 428 of the adaptor 300 are lifted abovethe drive flange 288, the central biased region 374 of the centralportion 308 (hidden in FIG. 12 but shown in FIG. 5 ) causes the firstleg 312 and the second leg 316 to snap back into the rest position,thereby capturing the drive flange 288 laterally between the first catch404 and the second catch 408 and vertically between the adaptor 300 andthe moving chassis 296. Since the cartridge 120 is secured againstvertical translation due to installation within the collar 266, andbecause the valve 284 is secured against vertical translation due tobeing fully retracted within the pump housing (not shown) at this stage,the drive flange 288 is not translated in the vertical direction as theadaptor 300 passes above it due to manual operation of the actuator 236.In this way, the drive flange 288 of the pump 248 becomes captured withthe drive unit 292.

Referring to FIG. 13 , the drive unit 292 has been translated verticallydownward back to an initial position, with the drive flange 288 capturedbetween the adaptor 300 and the moving chassis 296. In this initialposition, the first leg 312 and the second leg 316 of the adaptor 300are each simultaneously coupled to the moving chassis 296, e.g., by wayof the first latch 324 and the second latch 336, and to the drive flange288, e.g., by way of the first catch 404 and the second catch 408. Thedownward vertical translation is caused by the forces exerted by thesprings 472 between the collar 266 and the moving chassis 296, such thatthe moving chassis 296 is biased toward the initial position. Due to thedownward vertical translation of the drive flange 288 and, thus, thevalve 284 of the pump 248, the pump 248 has become primed by applying asuction to the cartridge body 252 of the cartridge 120 that pulls fluidinto the pump 248 for being dispensed upon an actuation and/or operationof the drive unit 292. As illustrated in FIG. 13 , the drive flange 288is engaged with the adaptor 300 and secured to the moving chassis 296 totranslate together vertically within the dispenser 110, such that whenthe actuator 236 is depressed in the longitudinal direction, the driveflange 288, adaptor 300, and moving chassis 296 all translate verticallyupward to a stroke position where fluid is dispensed. Then, the springs472 (see FIG. 14 ) exert sufficient force upon the moving chassis 296 tocause vertical translation downward that returns the drive flange 288,moving chassis 296, and adaptor 300 to the initial position. In thisway, manual operation of the dispenser assembly 100 is accomplished bystrokes, i.e., translation from the initial position to the strokeposition and then back to the initial position. Accordingly, the driveflange 288, the moving chassis 296, and the adaptor 300 are allconfigured to translate in a first direction, e.g., vertically upward,before the springs 472 (see FIG. 14 ) translate the drive flange 288,the moving chassis 296, and the adaptor 300 in a second direction, e.g.,vertically downward, to the initial position. In addition, by way of theactuator hinge 240, the actuator 236 is configured to be depressed in athird direction, e.g., longitudinally rearward, that is different fromthe first and second directions, although other configurations arepossible.

As illustrated in FIG. 14 , where the dispenser 110 is depicted in theclosed position, the actuator 236 is at a rest position, prior to beingdepressed or rotated about the actuator hinge 240. In the illustratedembodiment, the lever arm 242 is in contact with and pressed against theactuation surfaces 524 of the actuation docks 500, the spring 472 is ata rest position and extends approximately the full length of the post468, and the drive unit 292 is at an initial position. Accordingly, thedrive unit 292 and the actuator 236 are provided so as to avoid lostmotion, which can occur when movement of a first component does notcause movement of a second component that is directly linked to thefirst component. Here, movement (e.g., rotation) of the actuator 236about the actuator hinge 240 immediately causes vertical translation ofthe moving chassis 296 and one of the adaptors 300, 600, 700 wheninstalled therein. Thus, lost motion is avoided by the present actuator236 and drive unit 292 of the dispenser assembly 100, as depicted inFIG. 14 .

However, it is contemplated that the drive unit 292 can provide theability to effect lost motion with the actuator 236. For example, theactuator 236 may be provided with shortened lever arms 242 that do notcome into contact with the actuation surface 524 at the initialposition. Instead, a gap (not shown) may be present between the leverarms 242 and the actuation surfaces 524 of the moving chassis 296, suchthat only after the actuator 236 is pivoted about the actuator hinge 240some partial radial distance, e.g., between about 3 degrees and about 10degrees relative to the actuator hinge 240, the lever arms 242 come intocontact with the actuation surfaces 524 to cause vertical translation ofthe drive unit 292. In this exemplary way, lost motion may be achievedby the present dispenser assembly 100 to prevent short-strokes that maydamage or clog the pump 248 (see FIG. 3 ), among other performance anduser experience issues.

It is further contemplated that the dispenser assembly 100 incorporatingthe adaptor 300 (see FIGS. 11-13 ) can provide lost motion between thedrive unit 292 and the drive flange 288. For example, the adaptor 300may capture the drive flange 288 within modified first and secondchannels (not shown) that have a larger channel height EE1, such thatvertical translation of the drive unit 292 does not immediately causevertical translation of the drive flange 288.

On the other hand, it may be desired that the drive unit 292 restrictsthe amount of fluid dispensed. For example, with reference to FIGS. 14and 15 , a pair of shot restrictors 770 may be coupled to the movingchassis 296 to reduce the distance that the moving chassis 296translates during actuation. The shot restrictors 770 are provided inthe form of generally U-shaped clips that are removably coupled to theangled docking walls 512 of the actuation docks 500, as illustrated inFIG. 15 . The shot restrictors 770 are configured to allow the leverarms 242 to slide therealong when the front panel 130 is pivoted fromthe open position to the closed position (see FIGS. 1 and 2 ). Further,after the front panel 130 reaches the closed position, the shotrestrictors 770 cause the lever arms 242 to push the moving chassis 296vertically upward toward the collar 266 without depressing the actuator236. That is, the distance between the moving chassis 296 and the collar266 is reduced by the shot restrictor 770 being located between thelever arms 242 and the moving chassis 296. In addition, the shotrestrictors 770 reduce the vertical distance between the moving chassis296 and the collar 266 by extending over the upper end 516, between themoving chassis 296 and the collar 266. In this way, the shot restrictors770 are configured to reduce the distance that the moving chassis 296can translate in two directions, i.e., vertically upward and verticallydownward. By shortening the vertical translation distance of the driveunit 292, the distance that the drive flange 288 translates isshortened, particularly with respect to the priming stage or the returnto the initial position. In effect, this results in a modified initialposition that is vertically displaced above the original initialposition. As a result, the pump 248 is fully primed and, thus, lessfluid is pulled into the pump 248 for being dispensed by actuation ofthe drive unit 292.

Further, each of the adaptors 300, 600, 700 are associated with threedifferent states when received within the dispenser assembly 100. Forexample, in a first state, the adaptor 300 is received within the movingchassis 296 and no cartridge 120 is installed therein. In a secondstate, the adaptor 300 is received within the moving chassis 296 and afirst type of the cartridge 120 is installed therein, the adaptor 300and the cartridge 120 being compatible, i.e., the first catch 404 andthe second catch 408 of the first adaptor correspond to the drive flange288 of the first type of the cartridge 120 and/or pump 248 such that thepredetermined distance E1 is compatible with the diameter D2. In thissecond state, the first type of the cartridge 120 is capable ofdispensing a fluid by operation of the dispenser 110. In a third state,the adaptor 300 is received within the moving chassis 296, a second typeof the cartridge 120, different from the first type of cartridge 120, isinstalled therein, and the first adaptor 300 is not compatible with thesecond type of cartridge 120, i.e., the first catch 404 and the secondcatch 408 of the first adaptor 300 are incompatible with the driveflange of the second type of the cartridge 120 such that thepredetermined distance E1 is incompatible with the diameter D2. In thethird state, the incompatible drive flange is not captured between theadaptor 300 and the moving chassis 296 and, thus, the incompatible driveflange is not translated with the drive unit 292 to dispense fluid.Accordingly, the first, second, and third states of the adaptor 300 aremutually exclusive. It will be appreciated that the first, second, andthird states are identical for the adaptor 600 of FIG. 9 and the adaptor700 of FIG. 10 .

In some embodiments, the adaptors 300, 600, 700 are formed of a stiffplastic, e.g., polyoxymethylene (POM), acrylonitrile butadiene styrene(ABS), nylon, polyethylene, or any other suitable material withrelatively high stiffness and stability, although other materials may beused. The adaptors 300, 600, 700 are formed as a single, unitarycomponent, although multiple components or assemblies may be providedwithout departing from the scope of the disclosure.

It is contemplated that each embodiment of the adaptors 300, 600, 700may be provided with markings, indicia, coloring, or other means ofcommunicating aspects related to compatibility with one or morecartridges 120. For example, the adaptors 300, 600, 700 and thecorresponding drive flange 288 may each include an identical coloration,numerical symbols, or the like to indicate compatibility.

Further, it is contemplated that the adaptors 300, 600, 700 may beprovided as a kit with the corresponding cartridge 120. For example, thedispenser 110 may be provided with the body 140 and the adaptor 300 thatis configured to couple one type or version of the cartridge 120 to thebody 140. The adaptor 300 defines the predetermined distance E1 thatcorresponds to at least the diameter D2 of the drive flange 288 of thecartridge 120. Further, the dispenser 110 can be provided with theadaptor 600 that is configured to couple another type or version of thecartridge 120 to the body 140. The second adaptor 600 defines thepredetermined distance E2 that corresponds to at least the diameter D2of the drive flange 288 of the cartridge 120, which is different fromand incompatible with the predetermined distance E1. Accordingly, thedispenser 110 may be provided with both the adaptors 300 and 600, butonly one can be received within the body 140, i.e., within the slot 436of the moving chassis 296, at a time.

It is contemplated that the adaptors 300, 600, 700 may be provided withgreater or fewer numbers of catches and/or latches. In addition, it iscontemplated that the adaptor 300, 600, 700 may shaped differently thanshown. For example, the adaptor 300 may lack the latches 324, 332 whilestill being operably engaged with the drive flange 288 and receivedwithin the moving chassis 296. For example, central biased region 374and the predetermined distance E1 of the adaptor 300 provide for asnap-fit capture of the drive flange 288 of compatible diameter D2.Further, the adaptor 300 is received within the slot 436 of the movingchassis 296 and prevented from vertical movement, e.g., by the uppermember 440 and the lower member 444, lateral movement, e.g., by thefirst bumper 536 and the second bumper 548, and longitudinal movement,e.g., by the locator 386 in the pocket 390. Accordingly, it iscontemplated that differently shaped adaptors may be used within thedispenser assembly 100.

It is further contemplated that the dispenser assembly 100 may beprovided with an electronics module (not shown), e.g., a printed circuitboard (PCB), and a power source (not shown), e.g., a battery, formeasuring, recording, transmitting, and/or information related to theoperation and/or status of the dispenser assembly 100. In one example,an electronic module (not shown) records or counts the frequency withwhich the dispenser assembly 100 is used, such as with a magnet (notshown) that is coupled to the moving chassis 296 for verticaltranslation therewith to interact with a sensor (not shown) of theelectronic module (not shown) at particular coordinates.
